GRAIN-DRILL.

SPECIFICATION forming part of Letters Patent No. 410,438, datedSeptember 3, 1889. Original application filed October 29, 1888, SerialNo. 289,433. Divided and this application filed May 8, 1889. Serial No.'

To CLZZ whom it may concern:

Be it known that we, CHARLES PA'rRio and FRANK R. PACKHAM, citizens oft-he United States, residing at Springfield, in the county of Clark andState of Ohio, have invented certain new and useful Improvements inGrain-Drills, of which the following is a specification.

Our invention relates to improvements in grain-drills; and it alsorelates in its nature to certain constructions set forth but not ciaimedin our Letters Patent No. 4045108, issued May 2S, 1889, this applicationbeing intended as a division of the said patent.

The object of our invention is to provide a pressing and gagingattachment for graindrills of simple and novel character to be used inplace of the presser-wheels heretofore used.

Our invention consists in the constructions and combinations of partshereinafter described, and set forth in the claims.'

In the accompanying drawings, Figure lis a side elevation of a deviceembodying our invention. Fig. 2 is an elevation, enlarged, of the saine,showing the means of connecting the pressing attachment rigidly to theshoe when desired. Fig. 3 is a similar view showing the pressingattachment loosely attached to the shoe and in position for raising.Fig. 4 is a detailed section hereinafter referred to.

Like parts are represented by similar let-ters of reference.

In the said drawings, A represents the shoe of a grain-drill; B, thedrag-bar attached thereto.

The shoe A is composed of the runner a and the upper hollow portion a2in the usual manner. The shoe A is provided at the rear with abackwardly-projecting flange a3, provided with a series of openings a5.Below the flange a3 is a boss or projection a7.

C is the presser-foot, which is attached to the said boss a7 by a boltor pin b. The presser-foot C consists of a supporting-casting C',provided with a backwardly-extending bearing-support h', having a seriesof openings h2. Below the bearing-support ZJ is a saddle or seat h3,arranged at an angle to said bearing-support and adapted to receive aflexible runner or presser h5, preferably made of steel, and bolted orotherwise secured at its forward (No model.)

end to the seat b3 and projecting downwardly and rearwardly to adistance of about twothirds of its length, and then curved upwardly, asshown in the drawings. This runner or presser h5 is preferably madeslightly convex or rounding on its under surface, as shown in section inFig. 4. y

The supporting-casting C is provided with an upwardly and forwardlyprojecting spur 67, adapted as the presser-foot is moved about thepivoted connection l) to come against the upper portion a2 of the shoeand form astop for said presserfoot, as shown in Fig.

Extending upwardly from the bearing-support h is a connecting-rod c,preferably arranged with a spring-connection c, by which it is attachedto the presser-bar c2, arranged in the main frame of the drill in anysuitable and well-known manner and adapted to be connected to theraising and lowering mechanism, so that the shoes may be raised orlowered thereby, and a pressure applied to the said presser attachmentby increasing the tension of the said spring, as more fully set forth inour patent referred to.

Connected to the' iange a3 is a link-bar d, provided at each end withopenings d (Z2,

`adapted to receive a pin by which it may be connected to the saidflange and to the bearing-support h of the presser-foot.

The operation of the device is as follows: Y

'Vhen it is desired to use the presser-foot as a gage to regulate thedepth of planting, the link is connected to the bearingsupport and tothe flange, as above described, the openings in the ange furnishingmeans for adjusting the position of the foot as desired. Vhen thusconnected, by changing the position of the connecting-rod c along thebearing-support h, the pressure upon the shoe and presser-foot may bevaried by moving the point at which the pressure is applied to or fromthe point at which the shoe or hoe is pivoted. By disconnecting the link(Z a tienible presser attachment is secured, which permits the shoe andpresser-foot to rise independently of each other in passingobstructions, while the pressure applied may be varied, as before, so asto bring the pressure more or less on the shoe or piesseikfoot, asdesired. In lifting the shoe the stop 127 comes IOO against the shoe andprevents a further movement of' said presser-foot about its pivotedconnection as the bearing-'support h is raised, the lifting mechanismbeing attached to the connecting-rod c.

By having the runner??5 convex, as set forth, it is adapted to slidemore readily over the surface of the ground.

Ve have shown in the drawings our presser attachment in use with agrain-drill shoe. It is evident, however, that it may be used with anydesired form of shoe or hoe in common use with grain-drills.

A device as above described is adapted to be used in place of thepresser-wheels heretofore used for this purpose, andin certain soilsperforms its functions in a much more perfect manner than the wheels.

Having thus described our invention, We claiml. In a grain-drill, apresser-foot pivoted to the shoe or hoe and provided with a lower runnerand an upper bearing-support, and a connection from said bearing-supportto the lifting mechanism, substantially as described.

2. In a grain-drill, a presser-foot having a lower flexible runner, anupper bearing-support, and a stop projection to limit the upwardmovement of said bearing-support, substantially as specified.

3. The combination, with a grain-drill, of a presser-foot pivoted to ashoe or hoe and having a flexible runner and an upper bearingsuppOrt, aconnection from said bearing-support to the raising and loweringmechanism, and means for adjusting said connection along saidbearing-support, substantially as specified.

4. The combination, in a grain-drill and with the shoes or hoes, of aseries of presserfeet-one for each shoe or hoe pivoted thereto-saidpresser-feet each being pro vided with a lower flexible runner and anupper bearingsupport, a connection from each of said presser-feet to theraising and lowering mechanism, and means for connecting saidpresserfeet rigidly to the shoes or hoes, substantially as specified. i

5. The combination, with a grain-drill shoe, of a presser-foot having aflexible runner and an upper bearing-support, a series of' openings insaid bearing-support to connect the raising and lowering mechanism, astop on said presser-foot, and means, substantially as described, forconnecting said presser-foot rigidly to the said hoe or shoe indifferent positions of adjustment, substantially as specified. j

6. The combination, with a grain-drill shoe having abackwardly-extending flange with a series of openings therein and a bossor proj ection on the same side with said iiange, of

a presser attachment pivoted to said boss or' nection being providedwith an elastic or yielding portion adapted to exert a pressure on saidpresser-foot, substantially as specified.

8,. The combination, with a grain-drill hoe having abackwardly-extending flange with a series of openings therein, of apresser-foot pivoted to said hoe and provided with a lower iiexiblerunner, and an upper bearing-support having a series of openings adaptedto be connected by a link to the openings in said flange, a stop on saidpresser-foot, and a yielding connection from said bearing-support to theraising and lowering mechanism, substantially as specified.

9. The combination, with a grain-drill shoe or hoe, of a pressingattachment having a bearing-support pivoted to said shoe and a flexiblerunner connected to said bearing-support, said runner being convex incross-section on its bottom surface, substantially asspeciiied.

In testimony whereof we have hereunto set our hands this 4th day of May,A. D. 1889.
